Hi, I'm a hacker reporter (Report Crew)
3 days ago I found a hacker. So I open my OBS (Open BroadCaster) and I was recording
If I didn't recording, my fps was 250, and when I was recording I got 15 fps.
So my question is: How did it came like that? (btw I tried to set everything on fast and not fancy but didn't work).

So if you had fast, no lag before, it must have been an issue client-side. Either invest in some better recording software or find some other way to get fast gameplay recording. There is no one who can help you here and I recommend that this is closed
